Spokesman Glen T. Boyd says the Jefferson Parish Sheriff's Office received the report around 1 a.m. EDT Saturday about a car that had been shot multiple times just off a highway in Avondale, southwest of New Orleans. Bullet casings were scattered across the road and there were several bullet holes on the exterior of the car.

"Multiple bullet casings line the highway," Boyd said, according to NOLA.com. He added that no suspects have been identified at this time.

The male and female were pronounced dead at the scene. The children who survived were a 4-year-old girl and a boy approximately 4 months old.

The victims' identities were being withheld pending notification of family members.
